Pros:
I love the kingping stuff and being able to "steer" with 2 feet.
I love the straps, even with my board hanging on the lift no pressure points.
I love how my heel fits in the heel cup.
Damping... holy awesome comfy.

Cons:
The highback isn't adjustable at all other than forward lean.
The ratchets aren't as nice as burton's.
No toe ramp adjustment.

The big thing here. My Ions, SLX, and Driver X in size 9.5 all fit very snuggly into the heel cup and thus I get no lag toe or heel side. I always feel like burton ride a little loser. Even with adjustments.

Thanks

How would you rate response compared to cartels?

I can see your heel fits these better but does that comment refer to overall response?

I rock size 11s so I will need Large.

How about weight? Not a big deal but all the same how do they compare to cartels?

I ride 70% pow so dampening is not my main priority. I like to feel the snow as much as possible. Dampening is fine as long as it doesn't kill the feedback and feel from the powder.
